Abstract

The invention discloses a greenhouse breeding water and air parallelly heated solar energy-heat pump united heat supply system which comprises a solar water heating system, a soil heat storage and release system and a controller and further comprises a solar energy-heat pump air direct heating system and a new breeding water heating system. The solar energy-heat pump air direct heating system comprises a solar air heat collector group, a first heat pump and a fan. The new breeding water heating system consists of two portions, wherein the first portion comprises a sixth water pump, a waste heat exchanger, a sixth magnetic valve, a breeding water heat exchanger, a fifth magnetic valve, a breeding water preparation pond and a breeding pond. The soil heat storage and release system comprises a solar hot water heat collector group and a soil storage and release device. The greenhouse breeding water and air parallelly heated solar energy-heat pump united heat supply system changes an air and new breeding water heating mode in a breeding room, can decrease heat exchange middle links and is higher in heat transfer efficiency and better in energy-saving effect.

Description

technical field

[0001] The invention relates to a heating system for an aquaculture greenhouse, in particular to a solar-heat pump combined heating system in which aquaculture water and air are heated in parallel in the greenhouse. Background technique

[0002] According to the growth characteristics of aquatic products, aquaculture greenhouses in most areas of our country need heating in winter, which consumes a lot of energy. In order to save energy and reduce emissions, Chinese patent 201010039555.9 provides a "seasonal soil heat storage and release of solar energy-heat pump heating system for industrial turtle farms", the system uses solar energy as the main heat source, and uses soil to heat the solar collector in summer The excess heat collected is stored, and when the solar energy is insufficient in winter, the heat is taken from the soil to provide heat for the heating system, which has the advantages of good energy saving effect and low energy cost. However, the aq...
